Systematic behavior validation of most possible cases
|
|
|
=====================================================
|
|
|
|
|
|
This section tests most of the possible combinations of working directory
|
|
|
changes and inter-revision changes. The number of possible cases is significant
|
|
|
but they all have a slighly different handling. So this section commits to
|
|
|
generating and testing all of them to allow safe refactoring of the revert code.
|
|
|
|
|
|
A python script is used to generate a file history for each combination of
|
|
|
changes between, on one side the working directory and its parent and on
|
|
|
the other side, changes between a revert target (--rev) and working directory
|
|
|
parent. The three states generated are:
|
|
|
|
|
|
- a "base" revision
|
|
|
- a "parent" revision
|
|
|
- the working directory (based on "parent")
|
|
|
|
|
|
The file generated have names of the form:
|
|
|
|
|
|
<changeset-state>_<working-copy-state>
|
|
|
|
|
|
Here, "changeset-state" conveys the state in "base" and "parent" (or the change
|
|
|
that happen between them), "working-copy-state" is self explanatory.
|
|
|
|
|
|
All known states are not tested yet. See inline documentation for details.
|
|
|
Special cases from merge and rename are not tested by this section.
|
|
|
|
|
|
There are also multiple cases where the current revert implementation is known to
|
|
|
slightly misbehave.
|
|
|
|
|
|
Write the python script to disk
